MAGNETO DISTRIBUTOR CONSTRUCTION Filed Dec. 4, 1930 2 Sheets-Sheet 2 INVENTOR. bfrw/e .774@0? A TTORNE Y Patented Jan. 3, 1933 UNITED STATES PATENT OFFICE GUSTAVE J'. LANG, OF LONG-MEADOW, MASSACHUSETT;ASSIGNORhTO BOSOH MAGNETO CORPORATION, OF SPRINGFIELD', .MASSACHUSETTS, A CORPORATION NEW 'YORK Application led December 4, 1930, `Serial No; 499,960.

This invention relates to magnetos, and more particularly to an improvement in the construction of the distributor mechanism thereof. Y .v

An object of this invention, among others, is to provide a less costly and simplified construction of distributor mechanism, and particularly a distributor track member which will not be subject to carbonization.

More specially, it is an object of this invention to so simplify the` parts comprising the distributor that they may be readily moulded and assembled, and to eliminate a number of the usual brushes whereby the construction of said mechanism may be further simplified and made less expensive.

A further object of the invention is to make the track member of the distributor separate and of material different from the cover plate therefor; the trackmember bearing the contact segments through which the ingition circuits are periodically completed andthe plate or cover bearing means for attaching thereto the ends of the high tension conductors over which current flows to the igniters. The eX- pense and labor are thus reduced in comparison to what is involved in making a single distributor member carrying both the circuit closing Contacts and the means for securing the ends of the igniter leads. Y

A preferred embodiment of this invention is illustrated in the accompanying drawings, wherein Fig. 1 is a side view, partly in section, of a magneto embodying my invention; Fig. 2 is an elevation of the distributor plate; Fig. 3 is an elevation on the line 3-3 of Fig. 1; and Fig. 4 is an elevation on the line 4-4 of Fig. 1.

The magneto comprises the usual magnet 1, armature 2 mounted on the shaft 3, collector ring 4, distributor gear 5 driven by a gear 6 mounted on the shaft 3. Mounted on Vthe gear 5 and revoluble therewith is a distributing element or arm 7 having a conducting strip 8 making contact with brush 9 disposed in said element. The said brush 9 is arranged to revolve and make successive contact with the radially arranged conducting plates or segments 10, 10 of the distributor track member 11, which member is made preferably Vof Hitensit, a non-carbonizing material.

The said distributor track element is also provided with a center brush 12 which contacts with the conducting strip 8 `and a collector brush 13 which is in contact with the collector ring, the center and collector brushes being connected by a suitable conductor 14.

The distributor track member is joined toA `the distributor plate 15 by the screws 16, 16,

which provide also an electrical connection between the contact pieces 10 Vand the ter-l minals 1.7, 17 having the form of hollow metal bushings in the distributor plate and each of the segments in thetrack member. The metal bushings 17 are put inside hollow `bushings or bosses 21 integral with the distributor plate 15, these bosses being adapted to receive the ends of the high tension leads of the spark plugs.l rated to permit the screws 16 to pass through them into the threaded holes of the contact pieces 10. The distributor plate is in turn connected vto the magneto casing 18 by the screws 19, 19.

'The casing 18 of the magnetohas the form of a framework or housing shaped at one end to provide a casing for the gear 5 and member 11. It also encloses the armature chamber and mounts on its exterior the magnet or magnets 1.V On the end opposite the shaft 3, this housing has a bearing for a trunnion at the other end of the armature; and on the eX- terior of this opposite end is the usual casing for the magneto interrupter or timer. The part of the housing which constitutes the casing for the distributor gear 5 has a bearing The bushings 17 are perfo! 19 in which is the shaft or journal 20whieh sof A distributor including a stator having the form of a plate, hollow bosses extending through said plate, a member of non-carbonizing insulation material having Contact 5 pieces embedded therein engaging the inner ends of said bosses, hollowmetallic bushings atA the inner ends of said bosses and screws passing through the inner ends of said bushings and engaging said Contact pieces to secure the member and plate together and enable the Contact pieces to be Connected to conductors having their ends inserted into said bosses and engaging the. bushings. In testimony whereof I aHiX my signature. GUSTAVE J; LANG.`
